| 摘 要： | 噪声是影响光纤陀螺零漂指标的主要因素。为了降低光纤陀螺输出信号中的噪声含量,提高光纤陀螺的零漂指标,本文设计了一种自适应滤波器,用于光纤陀螺输出信号的数字滤波。设计的自适应滤波器采用基于最小均方误差准则的LMS算法,该算法的滤波准则是最小均方误差,采用递推的方法实现。设计的自适应滤波算法在数字闭环光纤陀螺中进行了实验,结果表明,设计的自适应滤波器能够降低陀螺输出数据中的白噪声,有效地提高了光纤陀螺的零漂性能。

| Abstract: | Noise is one of important factors which influence bias drift of fiber optic gyroscope(FOG).To reduce the proportion of the noise in output of FOG and improve the performance,a self-adaptive filter is designed.The self-adaptive filter is based on LMS algorithms,which rule is LMS and the method is recursion.The filter designed in FOG is tested.Experimental results show that the filter has an obvious effect on reducing white noise in FOG. |
